This is in regards to the (older non-variable) Zone VI studios cold light head for the Beseler 4x5 enlarger. This is the single tube type, not the more modern dual tube design.
From what I've read, this single tube type appears best suited for printing with graded papers, and that if I want to print on v-c papers, then there is a special filter for compensating the bluish coloured light. I've searched Calumet and Aristo's sites but haven't come across any information pertaining to this.
I would appreciate hearing from members who are actually using the older type tube, and what their solution has been for printing with v-c paper.
